Question 2210 out of 10 pointsCorrectGiven the following message, m(t), carrier, c(t), and Kp=0.12(rad/v), determine the PMmodulated signal equation and frequency bandwidth:m(t)=1.7cos(2π35E5t),c(t)=2cos(2π200E6Hzt).Selected Answer:Correctc.s(t)=2cos(2π200E6t + 0.204cos(2π35E5t)), BW = 8.4MHza.s(t)=1.7cos(2π35E3t + 0.1cos(2π200t)), BW = 9.1 kHzb.s(t)=1.7cos(2π35E6t + 3cos(2π200E6t)), BW = 18 kHzCorrectc.s(t)=2cos(2π200E6t + 0.204cos(2π35E5t)), BW = 8.4MHzAnswers:
d.s(t)=2cos(2π45MHz*t + 0.27cos(2π3.5kHz*t)), BW = 8.4 kHzQuestion 2310 out of 10 pointsCorrectSelect the OSI Reference Model Layer that identifies the port assignment identifying theapplication to which the data belongs at the destination node.
